Tips:
1. Rock sugar is used to adjust the sweetness and sourness of sour plum soup. If you are afraid of sourness, you can put more;
2. Adding too much licorice will cause bitterness, so just a little bit;
3. There is no need to add roselle. It is delicious only with ebony plum, dried hawthorn and rock sugar;
4. The flavor is best after being iced. Don't drink too much for gastric ulcers, which will stimulate the secretion of gastric acid;
5. It is best not to use iron or copper pots (haw haw, iron pots are not suitable for cooking acidic substances), casserole, glass, stainless steel are all acceptable.
